Cranston told TheWrap both he and costar Aaron Paul decided to get tattoos on the last day of filming the hit AMC show. Cranston has the show's "Br, Ba" logo etched on the inside of his ring finger on his right hand.

"Someone said, 'Well if you put it there, no one can see it,'" Cranston told E! "I said, 'I can see it.' So every once in a while I catch a glimpse of it, and I see that logo for 'Breaking Bad' and it just makes me smile.'"

Robert Downey Jr. and four of the original "Avengers" actors all have a matching letter "A." When turned on its side, you can see the number four, for the fourth "Avengers" movie coming in 2019.

According to Downey Jr., the tattoos were Scarlett Johansson's idea. The only original member who opted out of the ink was Mark Ruffalo. In his place, Chris Evans, Chris Hemsworth, Jeremy Renner, Downey Jr., and Johansson all gave tattoo artist Joshua Lord the same ink.

The singer got matching semicolon tattoos with the show's stars Alisha Boe and Tommy Dorfman, who play Jessica and Ryan, respectively, in April.

The semicolons are a symbol of new beginnings, made popular by suicide prevention organization Project Semicolon.

The "Pretty Little Liars" women got the first initial of their character's names inked on their index fingers to celebrate the end of the series. Hale, Shay Mitchell, Janel Parrish, Sasha Pieterse, Ashley Benson, and Troian Bellisario got the tattoos at the Shamrock Social Club in West Hollywood, California in October 2016.

"Thank you @shamrocksocialclub for taking care of us," Hale wrote on Instagram. "We couldn't not get tattoos to commemorate the show! And obviously on our 'shh' finger."

“Game of Thrones” stars Maisie Williams and Sophie Turner got matching tattoos to symbolize the date they were cast on the HBO show.

Turner showed off the tattoo at the 2016 Emmys red carpet. The actress, who plays Sansa Stark on "Game of Thrones," said she and her costar, Maisie Williams, had been thinking about getting matching ink for awhile.

"The date was always really significant," Turner said on the E! Red Carpet. "With 'Thrones,' we were always planning from season one, like if we make it all the way through, hopefully we could get a matching wolf or something. We don't know if we're going to make it, so Maisie and I were like, 'OK. Let's get these ones before anyone kills us.' Which is so possible."

The tattoo shows the House Stark direwolf sigil. Below the wolf head is a Ned Stark quote, "the pack survives." Turner's character says the words to Arya on the season seven finale of "Game of Thrones."

Orlando Bloom shared a throwback in October of some of the cast showing off their ink. They all got the word "nine" in different locations. Nine was the number of members in the fellowship who went on a quest to destroy the "One Ring" found by Frodo Baggins.

"We felt the experience was both wonderful enough and profound enough to have ourselves branded," Elijah Wood told Reuters Television, "so we went ahead and did that about a week before we finished."

“Spider-Man: Homecoming” actor Tom Holland got the Spidey logo on the bottom of his foot.

If you thought Cranston's tattoo was in a clever spot, Holland may have him beat. The "Homecoming" actor got the tat from celebrity tattoo artist Keith "Bang Bang" McCurdy while in New York City to commemorate landing the role of a lifetime.

"I always wanted to get that Spider-man symbol on the bottom of my foot, but I just never thought I would get it done," Holland told ABC10 reporter Mark S. Allen. "The opportunity came about and [Bang Bang] was like, 'Yeah we can do that.' And I had it done, and, yeah it was an amazing experience."

Holland said he actually had to have the painful tattoo done three times because it kept fading.
